Iscar 6000904 GTN-5 Cutoff Insert 5.1mm Carbide

Product Description

The ISCAR 6000904 is a single-end solid carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It uses a Self-Grip clamping method for secure tool holding during interrupted and continuous cuts. The insert carries manufacturer grade IC20, an uncoated carbide grade suited for a range of workpiece materials. With a cutting width of 5.1 mm (0.2008 inches) and a 7-degree relief angle, it delivers consistent chip clearance and edge stability across moderate to high production runs. Licensed machinists and toolroom operators are the primary users of this insert type.

This cutoff insert is appropriate for cut-off and parting applications on ferrous and non-ferrous materials in both production and job-shop environments. The neutral lead angle and neutral hand orientation make it compatible with standard right-hand and left-hand toolholder setups that accept GTN-5 series inserts. A 0.28 mm (0.011 inch) corner radius reduces edge chipping and helps maintain consistent part finish at the parting line. It is sold individually but carries a minimum order quantity of 10 units.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist or toolroom technician with the machine powered down and the spindle fully stopped. Use the appropriate insert seating tool or soft-faced mallet recommended by the toolholder manufacturer to seat the insert fully into the Self-Grip clamp. Inspect the insert pocket and clamping surfaces for chips or debris before seating a new insert. Follow the toolholder manufacturer guidelines for maximum depth of cut and feed rate to avoid insert fracture.
